It take place in testis
It take place whole life
In maturation phase many series of spermatogonia & residual spermatogonia are formed
Growth phase take place short period
Less growth during growth phase
No any division in growth phase
In growth phase primary spermatocyte formed
During maturation phase 4 spermatid formed
In this meiosis first then differentiation
sperms are motile
|
in ovary
45 to 50 years
Oogonia, accessory nurse cell & follicle cells are formed
long period
More growth during growth phsae
Meiosis start in growth phase up to diplotene stage
Primary oocyte formed
1 ovum and 3 polar bodies are formed
In this differentiation first then meiosis
Ova is immotile.
